[A case of erythema nodosum in tularemia].

Since 1980 some epidemics of tularemia occurred, involving large areas of Tuscany (Italy). Among the different clinical features described in the classic form of tularemia, erythema nodosum never has been reported. One case of erythema nodosum, the first reported in course of tularemia, is described. The correct diagnosis is based on careful question about exposure to mammals and ticks. The importance of early treatment is stressed.
